fd626d907e Remove debugging information
Problem: my dev machine returns a different value for `git config --get-all
secrets.patterns` than my CI machine... I ran `git-secrets --register-aws` to
get additional coverage, but it's still not the same. I created an issue on the
git-secrets GH repo to get better troubleshooting advice, but I don't need the
logging info. anymore, so I'm removing it.

56e4d9f9b5 Debugging briefcase pipeline
Somehow `git-secrets --scan-history` is exiting non-zero, when I don't think it
should. Logging some environment information to get a better idea of what's
going on.

3f3cba7c32 Define BuildKite pipelines in Nix
After a handful of failed attempts to run lint-secrets.sh due to a missing
`git-secrets` executable on my git server, I decided that now was a good time to
use Nix to define my BuildKite pipelines.

TL;DR:
- Delete ci/scripts directory
- Define ci/pipelines/{briefcase,socrates}.nix

Outside of this repository:
- I logged into my admin account at git.wpcarro.dev and changed my Gitea
  post-receive hook to trigger the briefcase pipeline
- I logged into my BuildKite account, deleted my build-briefcase pipeline,
  created a new briefcase pipeline that called:

  ```shell
  nix-build -A ci.pipelines.briefcase -o briefcase.yaml
  buildkite-agent pipeline upload briefcase.yaml
  ```

One day I will audit all of my ad-hoc, non-mono-repo activity (like the steps I
listed above) and attempt to fit everything herein... one step at a time,
though!

13daa560ba Testing new CI lint-secrets step
Adding a fake secret to test to the new CI build step. I'm not sure I expect
this to fail the step because it relies on a pattern that I defined in
.git/config... let's see!

5b6862ea39 Call git secret hide whenever //secrets.json is saved
Having `git secret hide` as a pre-commit hook doesn't make much sense to me. I
will detail why when/if I write a blog post on briefcase's secret mgt setup.

The problem is, if I change secrets.json and then run `git status`, I won't see
any pending changes. This is because secrets.json is gitignore'd. If I run `git
secret hide` everytime I save secrets.json, I can rest assured that my `git
status` will be consistent with any updates to secrets.json.

17c68d654b Prefer reading secrets.json to using pass show
I'm attempting to maintain a top-level secrets.json that defines all of the
sensitive data that I'd like to version-control without exposing everything in
cleartext to the world. To that end, I'm using `git secret`, which will use
`gpg` to encrypt secrets.json everytime I call `git secret hide` and decrypt
everytime I call `git secret reveal`.

I'm going to try this until I don't like it anymore... if that day comes...

I should write a blog post about my setup to solicit useful feedback and share
my ideas with others.

392832a1ca Testing git-secret
Adding a dummy, top-level secrets.json file using `git-secret`. It might be nice
to have a mono-secrets file in json because then I can use it with `jq` like:

```shell
$ jq '.secret' --join-output < ~/briefcase/secrets.json
```

cbaf74de0e Setup git-secret
This morning I'm attempting to secure my monorepo. How?

- `git secret`:  DONE: To version-control sensitive data
- `git secrets`: TODO: Lint code for sensitive data

I will probably update the CI to call `git secrets --scan` or some similar
command to fail when that exists non-zero. I have much to learn, but doing is
the best way to learn it.

4d8ce34a7e Simplify EXWM init hook
Anytime something before or during window-manager.el fails to evaluate,
I lose the ability to type, but I *can* still click.

@tazjin recommended that I use the mouse to cycle to the *Warnings*
buffer, which led me to another bug in a series of bugs that I'm
uncovering: ~/briefcase/org didn't exist.

A simple mistake like this should break my WM startup, so I decided to
remove most of my init hook logic.

9d7331d63b Debug evil-want-keybindings issue
Problem: dependency loading order

I originally assumed that keybindings.el was the first module to `require
'evil` because init.el shows:

```elisp
(require 'keybindings)
(require 'window-manager)
```

The problem is that keybindings.el calls `require 'window-manager` and
window-manager.el requires evil! I admit, I've created a bit of a birds nest for
myself.

A few thoughts:
- keybindings.el doesn't need to `require 'window-manager`. Fixed!
- window-manager.el shouldn't need to `require 'evil`. TODO...

39622607ff Add missing dependencies to emacs/default.nix
While debugging some broken Emacs config, I ran Emacs in X, where for some
reason my PATH doesn't have my nix-env dependencies... because of this, when I
call `~/.nix-profile/bin/wpcarros-emacs` to start my Emacs, I saw warnings about
missing packages that I hadn't seen before. Nice!

3dc7f7758b Drop support for wpc-keybindings
In favor of keybindings.el!

Now I have:
- kbd.el: There are no keybindings in this file. It's just a library for working
  with keybindings in Emacs.
- keybindings.el: (hopefully) all of my keybindings for EXWM, evil, etc.

0c71fc9d1d Drop support for dir-locals.nix, <nixpkgs>, etc.
In the spirit of Marie Kondo, I'm tidying up!

TL;DR:
- Prefer .envrc `use_nix` and delete all dir-locals.nix files
- Remove ~all references to <nixpkgs>, <unstable>, <depot> and prefer
  referencing each with briefcase.third_party.{pkgs,unstable,depot}
- Delete nixBufferFromShell function since I was only using that in
  dir-locals.nix files

51ec9e0d88 Move /home/wpcarro/nixpkgs-channels to /var/lib
My builds are still failing. This time with...
```
error: getting status of /home/wpcarro/nixpkgs-channels: Permission denied
```
...what confused me was the following:

```shell
$ sudo -u buildkite-agent-socrates stat /home/wpcarro/nixpkgs-channels
permission denied
```

But `ls -al /home/wpcarro | grep nixpkgs-channels` showed `r-w` for all users...

Thankfully @riking on ##tvl told me that I should check the permissions for
/home/wpcarro and /home...

After running `ls -al /home`, I saw `---` for all user... I then reproduced the
error by running:

```shell
$ sudo -u buildkite-agent-socrates stat /home
permission denied
```

Great!

So then I moved nixpkgs-channels to /var/lib/buildkite-agent-socrates. @edef
recommended that I read more about DynamicUser= setting for systemd, which looks
relevant after I took a cursory glance.

I'll also want a more declarative way to manager this, but I'm making small
improvements every day.

79904056af Move buildkite's SSH key out of /home/wpcarro into /etc/ssh
After enabling buildkite-agent using NixOS, it runs as its own user,
buildkite-agent-socrates, which does not have its own home directory. I moved
the SSH key that I made when running buildkite-agent as wpcarro into /etc/ssh
and `chown`'d it for buildkite-agent-socrates.

42efb3b08a Support build-briefcase.sh
For now, I'm supporting two CI pipelines:
- build-socrates
- build-briefcase

Conceptually, build-briefcase should cover what build-socrates does now, but
eventually I would like build-socrates to call `switch-to-configuration` so that
all of my websites, etc. stay fresh.

59f7481411 Revise previous opinions about absolute paths GT <bracket-notation>
Unforeseen problem: `buildkite-agent` runs its builds in a separate directory,
so if I want the `nix-build` command to build the newly checked out code, I need
to set <briefcase> to the CWD.

7833632a79 Attempt nix-build instead of nixos-rebuild switch
I've encountered a few problems with attempting to support nixos-rebuild:
- the activation step requires `sudo` privileges
- the `buildkite-agent` runs on the same machine, socrates, that is rebuilding
  itself. This means that when the activation step runs, it will attempt to
  restart `buildkite-agent` when the agent is still working

I'm slowly removing places in my nix code that rely on '<bracket>' notation, so
that I no longer depend on NIX_PATH being set. I still have more work to do.

{covid-uk,sandbox}/default.nix are breaking when I attempt to run my
build-socrates.sh script locally, so I'm temporarily disabling them until I can
get CI working as I expect.

to solve using Haskell. I'm having a good time, and I'm noticing strong and weak

reviewer gives me, and I'm storing my first drafts, second attempts, and
feedback here for now.

375c4a4c85 Restore shell.nix
I believe `use_nix` looks for shell.nix and then default.nix files, so I was

56b503c573 Prefer direnv's use_nix to shell.nix
I find it bothersome to share the list of Haskell dependencies between my
default.nix and shell.nix files. A few days ago, I created a THIRD file,
shared.nix, that defined the shared code b/w default.nix and shell.nix. This
DRY'd things up, but it also added a new file, which I didn't like.

Today I learned that direnv integrates with Nix using a function called
`use_nix`. Voila! I typically already have .envrc files per-project, so this
doesn't add any unnecessary files, and it allows me to delete my shell.nix
files.

I would use `lorri`, except that I encountered issues using Lorri on my work
computer, which I'm not interested in attempting to resolve now.
